I’ve been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I’ve been meaning to get UFW on it but I’ve been too lazy to do so. Is it a necessary thing that I need to have or it’s a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I’d say my server’s pretty secure but not the furthest I could take it. Opinions please?
I like to run ufw on all my machines but I’m also a tinfoil-hat wearing wacko who believes that no computer should ever really be trusted. Just trusted enough to do specific tasks.
